OpenThreads

This library is intended to provide a
minimal & complete Object-Oriented (OO) thread interface for C++
programmers. It is loosely modeled on the Java thread API, and the
POSIX Threads standards. The architecture of the library is
designed around "swappable" thread models which are defined at
compile-time in a shared object library. It is of importance to
note that while a factory pattern design could have been used to achieve
the goal of genaric interface, it would have required the programmer to
allocate each of the 4 fundemental types (Thread, Mutex, Barrier, &
Condition ) on the heap. Due to the cost associated with heap
allocation of the underlying concrete implementations of these
constructs on some platforms, such allocation was deemed unacceptable at
the time this library was originally written, and thus the factory
pattern was not used.

Instead, a somewhat obtuse - but
effective - technique was chosen to provide the necessary
data/implementation hiding. This technique uses private void
pointers to encapsulate object private data. The void pointers
actually point at concrete data structures, but give a uniform interface
to the dso.

It is the intent of the Open Thread
Group that the interfaces (header files) will be used to construct
optimized implementations using platform optimized multi-processing
constructs such as the sproc methods used on IRIX & Windows (tm)
threads on that Seattle based platform. There are currently
concrete implementations using both POSIX and Mircrosoft Windows (tm)
Threads in CVS.

Well gang, we're finally up and running on sourceforge!

How you
can contribute:

The OpenThreads library is currently pushing towards a stable 1.2
release. This release will entail POSIX and Windows (tm) Threads
concrete implemetations. If you find bugs, please file them online
here: Sourceforge
OpenThreads bug tracking page. If you have patches, please
send them to the maintainer: Sean Spicer (sspicer <at>
users.sourceforge.net). Please note however,
no patches will be accepted without a proper PGP signature, or being
sent via secure email using PGP. A free pgp-like implementation
can be found here: gnupg. The
maintainers public key can be found either at keserver.net or at the mit public keyserver, by searching on "Sean
Spicer". The proper keyID is: 15859D54, and the valid fingerprint
is: 8CED 19B7 3A3A BF54 B8E8 FB11 E044 F6B8 1585 9D54.
